Diagnostic Trouble Code Reference Chart

NOTE: Prior to performing any system test, see HOW TO USE SYSTEM TESTS under SYSTEM TESTS. On some models, PCM is capable of storing some body DTCs. If any "B" DTCs are retrieved (example DTC B1213), see appropriate MODULE COMMUNICATIONS NETWORK article in ACCESSORIES & EQUIPMENT to determine test to perform.

NOTE: If Powertrain Control Module (PCM) is replaced, new PCM must be programmed. See POWERTRAIN CONTROL MODULE (PCM) under PROGRAMMING. If Alternate Fuel Control Module (AFCM) is replaced, perform AFCM reset procedure. See ALTERNATE FUEL CONTROL MODULE (AFCM) under PROGRAMMING.
